What makes Scarpa\'s Instinct SR shoe a legendary slipper is found within its slightly asymmetrical and downturned shaped with it\'s medium angled toe box for a more focused toe power. A full microfibre upper combined with a REB reinforced elastic closure provide a strong fit for the life of the shoe. Top level hooking is provided by the ultra sticky Morphix rubber topper as well as a bi tension active randing system running from the toe to the arch of the foot to give great flex and subtle tension. 3.5mm 3/4 XS Grip 2 foot pad2mm XS Grip 2 heel underlayMorphix rubber ribHalf Length Flexan 0.9mm insert
